You’re looking at a listing and wondering **“Will this property actually make money?”** In the next few seconds you’ll learn a single‑page method that tells you if the rent hits the 1% rule—no deep‑dive cash‑flow model required. Grab the free spreadsheet, plug in the price and rent, and get a green or red signal instantly.  

## Why the 1% Rule Gets Misused  

Many investors waste hours building elaborate models before they even know if a property passes the **1% rule rental property** screen. The most common errors are:  

- **Mixing gross rent with net rent** – the rule compares **gross monthly rent** to the **purchase price**, not after‑expenses rent.  
- **Over‑engineering the formula** – adding mortgage, taxes, and repairs before the quick filter.  
- **Inconsistent checklists** – forgetting taxes, HOA fees, or market stability checks.  

These mistakes lead to analysis paralysis, missed opportunities, and costly false positives.  

## The One‑Page 1% Rule Calculator  

The solution is a three‑column spreadsheet that does the math for you in seconds.  

| Column | Input | Example |
|--------|-------|---------|
| **A** | Purchase Price | $150,000 |
| **B** | Expected Monthly Rent (gross) | $1,600 |
| **C** | 1% Check | `=IF(B2>=A2*0.01,"✅ Yes","❌ No")` |

**How it works:**  
1. Enter the asking price in **A**.  
2. Type the realistic gross rent you could charge in **B**.  
3. The formula in **C** instantly returns **✅ Yes** if rent ≥ 1 % of price, otherwise **❌ No**.  

Copy the row for every property you evaluate and you have an instant “go/no‑go” screen.  

## Quick 1% Rule Screening Checklist  

After the calculator gives you a green light, run this short checklist to avoid hidden red flags:  

- ✅ Verify the rent estimate with at least **two comparable listings**.  
- ✅ Confirm the neighborhood is **stable or growing** for rentals.  
- ✅ Identify any **major repairs** that could force the rent lower.  
- ✅ Ensure the HOA (if any) **doesn’t restrict rent increases**.  

Following the checklist keeps you focused on the big picture while still catching deal‑breakers the simple 1% screen might miss.  

## Real‑World Example  

I tested the tool on a duplex priced at **$150,000** with a projected rent of **$1,600**. The calculator displayed **✅ Yes** (1.07 % of price), giving me confidence to submit an offer the same day. No spreadsheet gymnastics, just a clear signal that the property passed the first filter.  

## Next Steps  

1. **Download the free 1% Rule calculator** (Google Sheets or Excel).  
2. Run every prospective rental through the **gross‑rent check**.  
3. If it passes, move to a detailed cash‑flow analysis; if not, walk away and save time.  

The 1% rule isn’t a guarantee of profit, but it’s a reliable gatekeeper that eliminates most overpriced deals before you drown in numbers.
